(The downside of this approach is that\nthese resources cannot be used as templates for setting the actual\ndevice\u0027s resources because they are missing from the template.) The\nkernel\u0027s APM implementation does not suffer from this problem and\nregisters all resources regardless of \"their size\".\n\nThis patch fixes a problem with (at least) the vintage IBM ThinkPad 600E\n(and most likely also with the 600, 600X, and 770X which have a very\nsimilar layout) where some of its PnP devices support options where\neither an IRQ, a DMA, or an IO port is disabled. Without this patch,\nthe devices can not be configured using the\n\"/sys/bus/pnp/devices/*/resources\" interface.\n\nThe manipulation of these resources is important because the 600E has\nvery demanding requirements. For instance, the number of IRQs is not\nsufficient to support all devices of the 600E. Fortunately, some of the\ndevices, like the sound card\u0027s MPU-401 UART, can be configured to not\nuse any IRQ, hence freeing an IRQ for a device that requires one.\n(Still, the device\u0027s \"ResourceTemplate\" requires an IRQ resource\ndescriptor which cannot be created if the resource has not been\nregistered in the first place.)\n\nAs an example, the dependent sets of the 600E\u0027s CSC0103 device (the\nMPU-401 UART) are listed, with the patch applied, as:\n\n Dependent: 00 - Priority preferred\n port 0x300-0x330, align 0xf, size 0x4, 16-bit address decoding\n irq \u003cnone\u003e High-Edge\n Dependent: 01 - Priority acceptable\n port 0x300-0x330, align 0xf, size 0x4, 16-bit address decoding\n irq 5,7,2/9,10,11,15 High-Edge\n\n(The same result is obtained when PNPBIOS is used instead of PnP ACPI.)\nWithout the patch, the IRQ resource in the preferred option is not\nlisted at all:\n\n Dependent: 00 - Priority preferred\n port 0x300-0x330, align 0xf, size 0x4, 16-bit address decoding\n Dependent: 01 - Priority acceptable\n port 0x300-0x330, align 0xf, size 0x4, 16-bit address decoding\n irq 5,7,2/9,10,11,15 High-Edge\n\nAnd in fact, the 600E\u0027s DSDT lists the disabled IRQ as an option, as can\nbe seen from the following excerpt from the DSDT:\n\n\tName (_PRS, ResourceTemplate ()\n\t{\n StartDependentFn (0x00, 0x00)\n {\n IO (Decode16, 0x0300, 0x0330, 0x10, 0x04)\n IRQNoFlags () {}\n }\n StartDependentFn (0x01, 0x00)\n {\n IO (Decode16, 0x0300, 0x0330, 0x10, 0x04)\n IRQNoFlags () {5,7,9,10,11,15}\n }\n EndDependentFn ()\n\t})\n\nWith this patch applied, a user space program - or maybe even the kernel\n- can allocate all devices\u0027 resources optimally. For the 600E, this\nmeans to find optimal resources for (at least) the serial port, the\nparallel port, the infrared port, the MWAVE modem, the sound card, and\nthe MPU-401 UART.\n\nThe patch applies the idea to register disabled resources to all types\nof resources, not just to IRQs, DMAs, and IO ports. At the same time,\nit mimics the behavior of the \"pnp_assign_xxx\" functions from\n\"drivers/pnp/manager.c\" where resources with \"no size\" are considered\ndisabled.\n\nNo regressions were observed on hardware that does not require this\npatch.\n\nThe patch is applied against 2.6.39.\n\nNB: The kernel\u0027s current PnP interface does not allow for disabling individual\nresources using the \"/sys/bus/pnp/devices/$device/resources\" file. Assuming\nthis could be done, a device could be configured to use a disabled resource\nusing a simple series of calls:\n\n echo disable \u003e /sys/bus/pnp/devices/$device/resources\n echo clear \u003e /sys/bus/pnp/devices/$device/resources\n echo set irq disabled \u003e /sys/bus/pnp/devices/$device/resources\n echo fill \u003e /sys/bus/pnp/devices/$device/resources\n echo activate \u003e /sys/bus/pnp/devices/$device/resources\n\nThis patch addresses only the parsing of PnP ACPI devices.\n\nChangeLog (v1 -\u003e v2):\n - extend patch description\n - fix typo in patch itself\n\nSigned-off-by: Witold Szczeponik \u003cWitold.Szczeponik@gmx.net\u003e\nCc: Len Brown \u003clenb@kernel.org\u003e\nCc: Adam Belay \u003cabelay@mit.edu\u003e\nCc: Bjorn Helgaas \u003cbjorn.helgaas@hp.com\u003e\nCc: Bjorn Helgaas \u003cbhelgaas@google.com\u003e\nCc: Henrique de Moraes Holschuh \u003chmh@hmh.eng.br\u003e\nCc: Matthew Garrett \u003cmjg@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "e57ee01750c4954fd0b5e3c6109cd4b870880eb9", "tree": "73356d5604cc10ca8e6e86616276da4531984004", "parents": [ "8f6b0dd369868559b384a66aa17512ae5aae2d9b" ], "author": { "name": "Uwe Kleine-König", "email": "u.kleine-koenig@pengutronix.de", "time": "Mon Jul 25 17:13:34 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jul 25 20:57:17 2011 -0700" }, "message": "drivers/rtc/rtc-tegra.c: properly initialize spinlock\n\nUsing __SPIN_LOCK_UNLOCKED for a dynamically allocated lock is wrong and\nbreaks the build with PREEMPT_RT_FULL.\n\nSigned-off-by: Uwe Kleine-König \u003cu.kleine-koenig@pengutronix.de\u003e\nCc: Andrew Chew \u003cachew@nvidia.com\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "8f6b0dd369868559b384a66aa17512ae5aae2d9b", "tree": "b98bcc40d158d96fe30af93e5bdede28fbeac77d", "parents": [ "9a9a54ad7aa2c7420c96c6fd33538f55d81775cb" ], "author": { "name": "Jesper Juhl", "email": "jj@chaosbits.net", "time": "Mon Jul 25 17:13:34 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jul 25 20:57:17 2011 -0700" }, "message": "drivers/rtc/rtc-twl.c: check return value of twl_rtc_write_u8() in twl_rtc_set_time()\n\nWe forget to save the return value of the call to\ntwl_rtc_write_u8(save_control, REG_RTC_CTRL_REG); in \u0027ret\u0027, making the\ntest of \u0027ret \u003c 0\u0027 dead code since \u0027ret\u0027 then couldn\u0027t possibly have\nchanged since the last test just a few lines above.

It will eventually\nupdate those bits ... in the struct page, but not in the PTE.\n\nAdditionally, it will not handle the lazy TLB flushing that can be\nrequired by some architectures in the fault case.\n\nBasically, gup is the wrong interface for the job. The patch provides a\nmore appropriate one which boils down to just calling handle_mm_fault()\nsince what we are trying to do is simulate a real page fault.\n\nThe futex code currently attempts to write to user memory within a\npagefault disabled section, and if that fails, tries to fix it up using\nget_user_pages().\n\nThis doesn\u0027t work on archs where the dirty and young bits are maintained\nby software, since they will gate access permission in the TLB, and will\nnot be updated by gup().\n\nIn addition, there\u0027s an expectation on some archs that a spurious write\nfault triggers a local TLB flush, and that is missing from the picture as\nwell.\n\nI decided that adding those \"features\" to gup() would be too much for this\nalready too complex function, and instead added a new simpler\nfixup_user_fault() which is essentially a wrapper around handle_mm_fault()\nwhich the futex code can call.\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: fix some nits Darren saw, fiddle comment layout]\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nReported-by: Shan Hai \u003chaishan.bai@gmail.com\u003e\nTested-by: Shan Hai \u003chaishan.bai@gmail.com\u003e\nCc: David Laight \u003cDavid.Laight@ACULAB.COM\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Darren Hart \u003cdarren.hart@intel.com\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "72c4783210f77fd743f0a316858d33f27db51e7c", "tree": "4efc95eb0aaade090bac42e72c5973ada6d2cdb1", "parents": [ "76d3fbf8fbf6cc78ceb63549e0e0c5bc8a88f838" ], "author": { "name": "Konstantin Khlebnikov", "email": "khlebnikov@openvz.org", "time": "Mon Jul 25 17:12:31 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jul 25 20:57:11 2011 -0700" }, "message": "mm: remove useless rcu lock-unlock from mapping_tagged()\n\nradix_tree_tagged() is lockless - it reads from a member of the raid-tree\nroot node.

In general, the complaints have not\nbeen about the workload itself unless it was a file server (in which case\nthe recommendation was disable zone_reclaim).\n\nThe stalls are mostly due to significant amounts of time spent scanning\nthe preferred zone for pages to free.

In many cases, there is less\nscanning as zone_reclaim simply gives up faster due to recent failures.\nThe second reason is that memory is used more efficiently. Instead of\nscanning the preferred zone every time, the allocator falls back to\nanother zone and uses it instead improving overall memory utilisation.\n\nThis patch: initialise ZLC for first zone eligible for zone_reclaim.\n\nThe zonelist cache (ZLC) is used among other things to record if\nzone_reclaim() failed for a particular zone recently. The intention is to\navoid a high cost scanning extremely long zonelists or scanning within the\nzone uselessly.\n\nCurrently the zonelist cache is setup only after the first zone has been\nconsidered and zone_reclaim() has been called. The objective was to avoid\na costly setup but zone_reclaim is itself quite expensive. If it is\nfailing regularly such as the first eligible zone having mostly mapped\npages, the cost in scanning and allocation stalls is far higher than the\nZLC initialisation step.\n\nThis patch initialises ZLC before the first eligible zone calls\nzone_reclaim(). Once initialised, it is checked whether the zone failed\nzone_reclaim recently. If it has, the zone is skipped. As the first zone\nis now being checked, additional care has to be taken about zones marked\nfull. A zone can be marked \"full\" because it should not have enough\nunmapped pages for zone_reclaim but this is excessive as direct reclaim or\nkswapd may succeed where zone_reclaim fails. Only mark zones \"full\" after\nzone_reclaim fails if it failed to reclaim enough pages after scanning.\n\nSigned-off-by: Mel Gorman \u003cmgorman@suse.de\u003e\nCc: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Christoph Lameter \u003ccl@linux.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "1d65f86db14806cf7b1218c7b4ecb8b4db5af27d", "tree": "01a2c4e3feb48327220b1fd8d09cf805c20eee7f", "parents": [ "d515afe88a32e567c550e3db914f3e378f86453a" ], "author": { "name": "KAMEZAWA Hiroyuki", "email": "kamezawa.hiroyu@jp.fujitsu.com", "time": "Mon Jul 25 17:12:27 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jul 25 20:57:10 2011 -0700" }, "message": "mm: preallocate page before lock_page() at filemap COW\n\nCurrently we are keeping faulted page locked throughout whole __do_fault\ncall (except for page_mkwrite code path) after calling file system\u0027s fault\ncode.
